Strike Industries FSASSTAB FSA Single Folder Stabilizer Black Steel Picatinny Rail Mount

The Strike Industries FSASSTAB FSA Single Folder Stabilizer is a Picatinny-mounted stabilizing brace designed for shooters who want a rigid, no-fuss folder that deploys instantly. Built with a strengthened steel hinge instead of aluminum, this stabilizer locks up tight with minimal play when extended—critical for consistent positioning at the range or in the field. It mounts directly to any 1913 Picatinny rail via M5 screw and locking plate, making it a straightforward add-on for AR pistols, short-barreled rifles, or other platforms that accept rail-mounted accessories.

What sets the Single Folder apart is its simplicity. Unlike stabilizers that require buttons, tools, or reconfiguration to fold, this one collapses to a single side on demand—no extra steps, no fumbling. Pre-assembled and ready to run, it shares compatible arm and modular end pieces with Strike's Dual Folding design, so if you ever want to upgrade or mix components down the line, parts will be familiar. The steel construction and tight tolerances mean you get rock-solid support without creep or rattle, whether you're running drills at 25 yards or setting up for longer shots.

If you run a modern tactical rifle platform and value a stabilizer that folds away instantly without complexity, this is a no-nonsense choice. The QD sling point adds versatility for shooters who prefer to keep their firearm tethered, and the black steel finish blends seamlessly with most setups.
